Abstract

Porous composite particles are provided which comprise an aluminum oxide component, e.g., crystalline boehmite having a crystallite size of from about 20 to about 200 Angstroms and additive component residue, e.g., silicate, phosphate, of a crystal size growth inhibitor, intimately dispersed within the aluminum oxide component. The aluminum oxide component of the composite particles are derived from a mixture of alumina trihydrate (e.g., gibbsite) and an alumina seed component, i.e., active alumina, which are both converted to crystalline boehmite in the presence of the additive component. Also provided is a method for making the composite particles, agglomerate particles derived therefrom, and a process for hydroprocessing petroleum feedstock using the agglomerates.
